Fiesta del Sol Mexican Sunflower

Fiesta del Sol Mexican Sunflower (Tithonia rotundifolia 'Fiesta del Sol')

Fiesta del Sol Mexican Sunflower brings bold, glowing orange color to summer gardens with a compact habit that fits easily into mixed borders and big containers. It blooms heavily in heat, giving you a steady run of daisy-like flowers that feel energetic without looking messy. This is a strong choice when you want pollinator action, cut-flower stems, and fast seasonal impact in one plant. Once it settles in, it handles hot weather with confidence as long as drainage is good.

Distinctive Features

This dwarf selection produces an abundance of single, bright orange, daisy-like flowers that are typically about 2 to 3 inches across, held above dark green, slightly hairy foliage. Plants branch well, creating a full, bushy look that stays more compact than standard tithonia types. Bloom typically runs from mid to late summer into fall, especially in warm weather, with flowers that attract butterflies and other pollinators. The plant is generally pest-light and often avoided by deer, making it a dependable performer for sunny, open sites.

Growing Conditions

• Sun: Full sun for best flowering and the strongest habit.
• Soil: Well-drained soil, including average to poor soils, and avoid heavy, consistently wet ground.
• Water: Medium moisture to establish, then low to medium water once rooted, with deep watering during extended drought.
• USDA Zones: 2 to 11 as a warm-season annual.
• Mature Size: About 24 to 36 inches tall and about 18 to 24 inches wide.
• Notable Traits: Heat tolerant, drought tolerant once established, and excellent for pollinators and cut flowers.

Ideal Uses

• Focal Point: Use a bold grouping as a focal point in a sunny bed where the orange blooms can carry the scene from mid summer into fall.
• Pollinator Gardens: A strong nectar source that draws butterflies and keeps the garden active late in the season.
• Cut Flower Gardens: Provides bright stems for informal bouquets without sacrificing the garden display.
• Sunny Borders: Adds reliable height and color in the middle to back of the border without overpowering nearby plants.
• Large Containers: Works well in big pots where you want a fast, summer-long color statement in full sun.

Low Maintenance Care

• Watering: Water consistently during the first few weeks, then shift to deeper, less frequent watering as roots develop.
• Soil Fertility: Avoid heavy feeding, since overly rich soil can produce weak stems and fewer flowers.
• Support: Provide light staking only if grown in windy sites or overly rich soil where stems may lean.
• Deadheading: Remove spent flowers to keep the plant tidy and encourage continued bloom.
• Season Timing: Plant after frost risk has passed and warm weather is established.
